SPECIFICATION forming part of Letters Patent No. 308,416,61ated November 25,1884.

Application iiled May S, 1883.

(No model.) Patented in France August 2, 1852, No. 150,429.

To all whom it may concern.-

Be it known that I, ANATOLE LasiroLEs, a citizen of the French Republic, residing at Ohateauroux, in the French Republic, have invented certain new and useful Improvements in Time-Detectors, (for which I have obtained Letters Patent in France, dated August 2, 1882, No. 150,429,) and I do hereby declare the i'ol lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the let ters marked thereon, which form a part of this specification.

The invention relates to improvements in electric time-detectors; and it consists in the construction, arrangement, combination, and co-operation of a time and detector mechanism, the latter operated electrically, and means for producing the record of the operation of the detector mechanism, substantially as here inafter described, and shown in the accompanying drawings, in which Figure 1 is an elevation of part of the detector and time mechanisms, the electrical connections of the former and two stations, and their electrical and recording devices, the face of one of the dials of the station-indicators, as well as the face of the main indicator and the inclosing-casings, being removed. Fig. 2 is a sectional edge view ot'thetime-detector. Fig. Fig. 4 is a like view of part of the mechanism shown in Fig. l to more clearly illustrate certain parts thereof. Fig. 5 is a rear face view, the back supporting-plate being removed. Fig. '6 is a side elevation of a portion of the time and detector mechanisms shown in Fig. 2. Figs. 7 and 8 are perspective detail views of parts of the detector mechanism.

The system is composed of any number of stations, two of which are shown in Fig. 1 as anexample, and these stations may be located at any desired distance from the main indicator. Each station has an indieatordial, 1), having any desired number of subdivisions, according to the number of records desired to be made in a given time. The dial is loosely mounted on an arbor, a, that carries a ratchetwheel, 9*, in rear of the dial and an indexhand, h, in front thereof, both rigidly secured to the arbor. Fach station is also provided vith an eleetro-magnet, M, and the electromagnets of all the stations are connected with any suitable battery or generator of electricity and with an electroanagnet, M, of the principal detector mechanism. The armatures m of the station electro-nragnets M carry each a pawl, 1), held in engagement with the ratchet r on arbor a by an adj Listing-screw, s, a pawl, p holding the ratchet against backward rota tion. J J are adjustingscrews for regulating the amplitude of the vibration of the arm-(.- ture m.

It is obvious that if the normally-interrupted lnittery-circuit is closed by any convenient 1neansas, for instance, the usual circuitbreaker or contact-button, on the depression of which the circuit is closed by a metallic eonnectionthe armature m will be attracted and the ratchet-wheel rotated the distance of one tooth, and with it the index-hand the distance of one subdivision of the dial, the ratchet having of course a number of teeth equal to the number of subdivisions on the dial. In this manner a record is made at each station whenever the electric circuit is closed. Of course it will be understood that these devices are suitably inclosed in a casing, and that the buttons or other means employed for closing the electric circuit are alone accessible to the person charged with making the records.

The devices just described are in themselves not new, and I do not desire to claim them, except in so far as their combination and co operation with the mechanisms presently to be described is concerned.

D is the dial of the main indicator, having the usual hour and minute subdivisions and hour and minute hands H H.

\Vithin the above subdivisions the dial has two annular ridges, d (I, over which an annular strip or ring ot'pa )er, d,is laid, and stretched thereon by means of the annular stretchers (Z as more clearly shown in Fig. 2.

\Vithin the inner annular rib formed by the stretchers (Z and the ribs (1 of the dial D is formed a second dial, D subdivided into any number of subdivisions. In practice these subdivisions equal in number the total number of subdivisions of the dials D of all the stations; hence it four stations are connected with the main indicator, and the dial of each station has ten subdivisions, the dial D should have forty subdivisions, as shown in Fig. 3, so as to totalize the records indicated by the dials of all the stations, a hand, H indicating the sum of the records.

The mechanism of the main indicator is mounted in and supported from two plates, 1? P, secured to pillars I, upon which the dial D is also supported, the whole being inclosed in a suitable case, which I have deemed unnecessary to show, and said mechanism is com posed of a train of registeririg-gearing and a train of clock-gearing, operated from two independent spring-barrels, B B, Fig. 2, respectively.

Any suitable clock mechanism may be employed, and as such mechanism is well known it will not be necessary to describe the same in detail, except insofar as regards those ele ments thereof which cooperate with the detector mechanism.

The main transmitting-wheel is indicated by w, Fi 2, the hour and minute hand wheels by trw, and the transmitting-gear by 'w'flFigs. 1, 2, and 4-, and I) I) the squared shafts and ratchet and pawl devices for winding the springs of the barrels B B, respectively. Of course it will be understood that the clock mechanism just described controls the movements of the hour-hand H and minute-hand ll of the detector only, the movements of the hand H being controlled by the detector mechanism, which I will now describe.

The main arbor A carries the minute-hand H and wheel to, also the hour-hand barrel S, carrying the hounhand H and wheel 20, said barrel having at its inner end' a groove, 3, formed by two annular flanges, s s, for purposes presently explained.

Upon thebarrel S is loosely mounted a barrel, S-, that carries the indicator-hand H and a ratchet-wheel, \V", supported from a cock, If, in rear of the dial 1), as shown in Figs. Li. and 2, said ratchet-wheel being held against free rotation in one direction by a sprin g pawl, c. The spaces between the teeth ot'the ratchet wheel relatively to the spacing of the dial 1) is such that when the wheel is rotated a distance of one tooth the hand H will move from one graduation to the next succeeding one on the dial. The ratchetwhcel is controlled by and operated through the electro magnets of all the stations in the following manner:

M is an elcclro-magnct in electrical communication with the elcctro-magnets ill of all the stations by suitable metallic connections, which. I have deemed unnecessary to show, since such connections are too well. known to need either illustration or description. The armature m of the electromagnct M is con nectcd with a lever, L upon an arbor, AG, by a connecting-rod, 11-, and said arbor carries a pawl, B", that is normally in engage ment with one of three or more peripheral notches, c, ot'adisl,E. Thelatteris mounted on an arbor, A, that carries a pinion, G, Figs. 2, 5, and 6, driven from the spring-barrel, B, and a gear-wheel, N, that meshes with a pinion, l', 011 an arbor, A The disk E also carries on its outer face three or more pins, F, in the path of the teeth of the ratchetwheel \V,a1id upon said disk it are also formed a like number of wedgeshaped projections, G, in the path of an angular arm, Z, of alever, L, pivoted at Z upon plate P. The opposite end of the lever L is forked, as shown at K, Fig. 4, the branches of the fork lying in the groove 3, formed by the flanges s s of the barrel S of the hour-hand H.

It is obvious that when the electric circuit is closed at one of the stations the armature m of the clect-romagnet M is attracted, and through the rod R the arbor A is partially rotated,thereby withdrawing the pawl B from its notch c of the disk E, which pawl will i1nmediately, Oll thcinterriqption of the circuit, move back on the disk 15. As soon as said pawl is disengaged from the disk the latter will be rotated by the springpower through pinion C until the said pawl engages with the next notch. During this rotation of the disk one of the pins F will rotate the ratchet wheel \W a distance equal to one tooth, and the hand H from one subdivision to thenext succeeding one on the dial 1). At the same time one of the wedge-shaped projections G will move one end of the lever l on its pivot outwardly, the forked end moving inwardly against the tension of a forked spring,.T, drawing the sleeve S and the hour-hand H with it,the latter being provided on its under side with a perforator, h, that perforates the strip or disk of paper (2. The forked spring J, also cmbracing the barrel S, acts to return thcbarrel into its normal position, as plainly shown in Figs. 2 and 4. By this arrangement of devices a visible indication is made at each station of the number of times the electric eurrcnt has been elosedthat is to say, of the number of indications made by the watclnnan at such. station. A like indication is made by the main indicator of the total closures of the electric circuit at all the stations, and simultaneously therewith apermanent record thereof is made by the main recorder, that also shows the precise time at which the electric circuit was closed at any one of the stations; and by locating the station-indicator below the main indicator, either in the same case or in a separate case, the precise station at which the electric circuit was closed may be noted by the officer of the watch.

It is obvious that by employing a recordstrip, (1, having hour and minute subdivisions corresponding with those on the clockdial,

the time of each record will be permanently.

indicated thereon.

In order to notify the officer of the watch whenever the electric current is closed, an audible signal is given by the main indicator in the manner and by the instrumentalities as follows.

As above described, the arbor A carries a gear-wheel, that meshes with a pinion, I,

on an arbor, A that also carries an escapement-wheel, N, controlled by an eseapement lever or anchor, 02, pivoted upon plate 1?. The arbor A also carries a gear-wheel, O, and a bell-hammer, Q. The wheel 0 meshes with a pinion, t, on an arbor, A", which latter also carries a gear-wheel, t, that meshes with a pinion, c, on arbor V, which carries the regu lating-fly XV. The arbor A also carries a le- Ver, K extending upward and provided at its upper end with a flat lug, If, that projects through a slot in plate P into the path of a pimp, secured to the face ofthe gear-wheel '6.

As shown in Figs. 1 and 4, the lever li" is held by a spring, 0 in the end of the slot with the lug 111 the path of the pin 1) ofgear-wheel t, thus holding the entire train of detectorgearing against movement, said spring 0 also holding the pawl B in engagement with the disk E. \Vhen, however, the armature m of the electromagnet M is attracted on the closing of the electric circuit at one of the stations, the arbor A is partially rotated to disengage the pawl 13 from the disk E, the lever K being simultaneously moved toward the opposite end of the slot, with its lug if out of the path of the pin 19, thus permitting the spring motor to move the train of detector-gearing, thereby causing the hammer Q to strike upon a gong, Q, a number of blows in rapid suc cession controlled by the escapement, and by the time of rotation of the disk Ethat is to say, by the distance traveled by the disk before its movement is again interrupted by the engagement of the pawl 13 with one of the notches e.

As above stated, the disk has three or more notches or stops, three being shown in Figs. 1, 4, 7, and S, and four being shown in Fig. 2. Consequently the hammer will rapidly strike the bell or gong Q during onethird or onei'ourth of a revolution of the disk E.

I do not desire to limit myself to the number of teeth on the ratchetwheel W or stop notches or pins or wedge-shaped projections on disk E, as it is evideut't-hat these may be varied-without changing the function thereof.

It is obvious that should any watchman require assistance he is enabled to sound an alarm by keeping the current closed for such a length of time as to cause the hammer to strike a greater number of blows on the gong.

The permanent record will then be indicated by two or more perforations in the paper (1, in proximity to each other, thereby also indicat ing the time at which such assistance was asked.

Having now described my invention, what I claim, and desire to secure by Letters Patent of the United States, is
